I'm familiar with the flickrRSS plugin, which allows small thumbnails from Flickr to be posted on a widget. Since all MagPress themes support the same functionality, it seems to be a waste to duplicate the functionality, and get rid of that plugin.
However, I stumbled upon a slight issue. Apparently, I cannot get the built-in Flickr widget to display group ("pool") pictures. It only seems to work with pictures from individual persons. I thought that the only thing needed was to figure out the group/pool Flickr ID and everything ought to work, but, apparently, while this is the case with the flickrRSS plugin, the built-in MagPress Flickr widget seems to work differently.
Is there a trick to get it working with group/pool pictures as well?
